PATENT OFFICE..

IMPROVED HANGING-MACHINE.

Specicaton forming part of Letters Patent No. 93,7320, dated August 3, 1869.

To all whom, it may concern:

Be it known that I, SETH LOWEN, of Temperanceville, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Flanging-Ma-Y chines; and/I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon. f

The nature of my invention consists in the combination and arrangement of an adjustable centering-piece, adjustable fianging-disks, and friction-rollers, said centering-piece, 'flanging-disks, and rollers being constructed, arranged, and operating with relation `to each other as hereinafter set forth. i

To enable othersV skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

In the accompanying drawings, which form part of my specification, Figure l, Sheet A, is a side elevation of my improvement in danging-maehines. Fig. 2, Sheet A, isa top view or plan'of the same. Fig. 3, Sheet B, is a side elevation of the same, and represents a plate -arranged in the machine for being flanged.

In the accompanying drawings, A represents an. iron frame, provided with an upright piece, m, in which 'are arranged adjustable bearings for the shaft w of the disk J. To one of the bearings of the shaft w are attached friction-rollers k, which are used for the purpose of holding the plate o to be flanged down on the disk h, the shaft u of which has its bearing in the piece marked B, which may be moved back and forward on the frame A through the medium of the screw n. The bearings of the shaft w and the friction-rollers k are raised and lowered through the medium of the screw i. The adjustable centering-piece, consisting of the parts g, f, and e, is so arranged with relation to the piece B that it can be moved back and forward on the piece B, so as to change the position of the center point, e, with relation to the disks h and J. The part of the centering-piece marked g is fitted to the part so thatit will move back and forward on a straight line with'the center of the disk h, and is held in a fixed position at the point desired by means' of the set-screw s.v

The object of arranging the several parts so 1 that they can be adjusted as hereinbefore described is for the purpose of adapting the ma? chine to the flanging of plates of differentdi-l ameters and of different thicknesses.

As the construction of myy improvement in Hanging-machines and the relation that the several parts bear to each other will readily be understood from the foregoing description and by reference to the accompanying drawing/s, therefore, without further description of t its construction, I will proceed to describe vits operation, which is as follows: The disks 7i and vJ and the centering-piece are adjusted and ari ranged to suit the diameter and thickness of the disk or boiler-head to be flanged. disk or plate o for ythe boilerfhead is then placed in the centering-piece, as shown in Fig.

3 of Sheet B. The centering-point e is then turned or screwed down, so as to form a pivot or axis for the revolving of the plate o. Motion is .then imparted to the disk by applying power to the crank x and the revolving of the disk h. The disk J will be revolved through i the medium of gear-teeth on disks h and J, which mesh into each other, and the revolv-v ing of the disks h and J will rotate the plate or disk o and bend down the desired ange.

tion, and operation of my improvement, what I claim as of my invention 'isrIhe combination and arrangement of the adjustable centering-piece consisting` of parts g, f, and c, slide B,'disks h and J, and adjustable friction -rollers k, the whole being con'- structed and voperating substantially as herein described, and for the purpose set forth.
